Researches in the Laboratory for Advanced Biotechnology and Biomedical micro-Instrumentation (LABBI) have been emphasized on development of new analytical methods and instrumentation applicable especially to biomedical and environmental fields. Recently, the miniaturization of chemical and biomedical instrumentation has become the major area of our research, and we have developed a variety of key technologies in lab-on-a-chips and DNA chips. Development of bionanostructures and bionanofactories are also within the scope of our research. Single cell analysis and single biomolecule engineering are the leading projects in this area. LABBI has been designated as a 'National Research Laboratory' by the Ministry of Science and Technology, South Korea, since 1999.
